5

CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION,

Agreement (an Added Product). If Manufacturer elects to include Added Product, Manufacturer shall provide Distributor prior written notice of such election (the Added Product
Election), together with the Supply Price for such Added Product (the Added Product Supply Price). The Added Product Election shall de deemed to amend Exhibit 3.1 to establish the Added Product Supply Price.
The Supply Price for such added Product shall be determined in accordance with the same criteria as the Supply Prices set forth in Exhibit 3.1. Following such Added Product Election, such added Product shall be deemed a
Product for all purposes hereunder. Distributor shall launch such added Products within *** (***) business days after the later of (x) Distributors receipt of the Added Product Election, and (y) Distributors
receipt of launch quantities of such added Products.

2.3 Supply and Commercial Exploitation. Distributor shall
purchase all of its requirements of the Products exclusively from Manufacturer and in accordance with this Agreement. The purchase price paid by Distributor for Products shall equal the Supply Price payable under Section 3.1 plus the percentage
of Net Distributable Profits payable under Section 3.2. Distributor shall use commercially reasonable efforts to distribute, promote and expand the sale of the Products as generic products in the Territory. In promoting and distributing the
Products, Distributor shall not use the Trademark or any other trademark or trade name, except that Distributor may, in a manner consistent with Applicable Laws and subject to the provisions of Section 6.4: (a) use the Trademark on
promotional materials to the extent necessary to indicate that the Products are substitutable for the Branded Products and are authorized generics of the Branded Products, and (b) identify itself as the distributor of the Product
using its Prasco trade name and trade dress.

2.4 Limitation on Distributing Competing Products.
Except for Distributors distribution and sale of the Products in accordance with this Agreement, during the Term, Distributor shall not, and Distributor shall cause its Affiliates to not, purchase, manufacture, supply, promote, advertise,
merchandise, distribute, sell or offer for sale, directly or indirectly any Competitive Product in the Territory. During the Term, Manufacturer shall not distribute or sell or authorize or permit the distribution or sale of any Product or Products
as a generic product in the Territory other than through Distributor.

2.5 Distribution Obligations. Distributor
shall comply with all Applicable Laws and act in a manner consistent with industry practices as a pharmaceutical distributor, including: (a) store, handle and distribute its inventory of the Products in clean and sanitary conditions as required
to maintain the quality and traceability of the Products, and in accordance with the labeling for the Products; (b) not alter the Products in any manner; (c) comply with the Act and all other applicable federal, state and local food,
health and other relevant laws and regulations within the Territory in connection with its distribution and sale of the Products; and (d) not promote or market the Products in any manner which is inconsistent with the labeling of the Products
or applicable laws and regulations (including without limitation, 21 CFR Section 201), or otherwise make any false or misleading representations to customers or others regarding the Products.

2.6 Solicitation Outside Territory. Distributor shall not, and Distributor shall cause its Affiliates to not
(a) solicit orders for sales of any Product or Products to any existing or prospective customer outside the Territory, (b) deliver or tender (or cause to be delivered or

6

CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION,
WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH AN ASTERISK ***, HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION

tendered) any Product or Products outside of the Territory, or (c) sell any Product or Products to, or solicit any sales from, a customer if Distributor knows or has reason to know that such
customer intends to resell the Products outside of the Territory.

2.7 Pricing. Distributor shall have sole
discretion in establishing the prices at which Distributor sells the Products. In exercising its pricing discretion, if Distributor or its Affiliates sell Products to a customer who also purchases other products or services from Distributor or its
Affiliates, then Distributor agrees not to, and shall require its Affiliates not to, allocate the sales price of the jointly-purchased units of the Product and the other products or services, or any discounts offered in connection therewith, in a
manner that is reasonably likely to disadvantage Distributors Net Sales of the Products in order to benefit sales or prices of other products or services offered by Distributor or its Affiliates. Distributor also agrees that if it violates the
foregoing prohibitions, including if it prices the Products in order to gain or maintain sales of other products, then for purposes of calculating the payments due hereunder, then, in addition to any other remedies available to Manufacturer, the Net
Sales shall be adjusted to reverse any discount or other incentive provided by Distributor that was in excess of customary discounts for the Products (taking into consideration all relevant data for the Product, including similar products marketed
under similar market conditions by Distributor and/or similarly situated distributors).

2.8 Reservation of
Rights. Except as expressly provided in this Agreement, Manufacturer is not granting to Distributor any right, title or interest, whether express or implied. Nothing in this Agreement shall preclude or prevent Manufacturer or its Affiliates
from manufacturing, marketing or selling the Branded Products (either by itself or through a Third Party) in the Territory, except that during the Term, Manufacturer shall not authorize the distribution or sale of any Product or Products as a
generic product in the Territory other than through Distributor. Except as set forth in Section 2.1, nothing contained in this Agreement shall grant (or be construed as granting) to Distributor any right, title or interest in, to or under any
NDA held in the name of Manufacturer, or any supplement thereto, or any other intellectual property right owned or controlled by Manufacturer.

2.9 Product Listing; NDC#; Manufacturer. Distributor shall be responsible for complying with the Product Listing requirements with respect to the Products. Distributor shall distribute and
sell the Products using only a NDC# that reflects Distributor as the distributing and selling party. Distributor shall take all actions necessary to obtain such new NDC# prior to the Commencement Date with prior notice to and approval from
Manufacturer.

2.10 Contract Manufacture. Distributor acknowledges and agrees that Manufacturer uses Affiliates
and/or Third Parties to contract manufacture or package the Products. Manufacturer acknowledges and agrees that such arrangements shall not limit Manufacturers obligations under this Agreement, subject to the provisions of Section 10.7.

ARTICLE 3

FINANCIAL PROVISIONS

3.1 Supply Price.

(a) Distributor shall
pay Manufacturer a supply price for the Products on an SKU basis. The initial supply price for each Product is set forth in Exhibit 3.1, and each such price shall be subject to adjustment from time to time as set forth herein. With respect to
each Product, the price set forth in Exhibit 3.1 as adjusted from time to time as set forth herein is referred to as the Supply Price.

(b) The Supply Price for each Product shall remain firm for so long as Manufacturers Actual Cost for that
Product has not changed. Upon a change in Manufacturers Actual Cost for a Product, the Supply Price for that Product shall be increased or decreased (as applicable) to reflect Manufacturers Actual Cost for that Product on a first-in
first-out basis. Manufacturer shall promptly give Distributor written notice of any change in its Actual Cost.

(c) In no event shall the Supply Price be less than Manufacturers Actual Cost.

(d) The term Actual Cost means (i) Manufacturers documented costs paid to its Third Party
manufacturers for Products, plus (ii) the amount included in the per carton Supply Price set forth in Exhibit 3.1 relating to the cost of one full-time equivalent employee allocated to support the Products. (The amount in item (ii) is not
subject to change during the Term.)

3.2 Net Distributable Profits.

(a) Following the Commencement Date, and during the remaining Term, Distributor shall pay Manufacturer a
percentage of Net Distributable Profits per quarter as specified in Exhibit 3.2 and shall make such payments in accordance with Section 3.3. For purposes hereof, a quarter is measured as follows: (i) for the first
quarter, the stub period beginning on the date of the First Commercial Sale and ending on the last day of the calendar quarter (March 31, June 30, September 30 or December 31) in which the First Commercial Sale occurs;
(ii) for the next succeeding quarters, the full calendar quarter period; and (iii) for the final quarter, the stub period beginning on the first day of the calendar quarter and ending on the termination or expiration of this Agreement.
Notwithstanding the foregoing, if the First Commercial Sale occurs on a date that makes the first stub period less than two months, then for purposes of this Agreement, the first quarter shall be the period beginning on the date of the
First Commercial Sale and ending on the last day of the first full calendar quarter after the stub period.

(b) The Parties acknowledge that the deductions from Net Sales set forth in Section 1.28(b) shall be accrued
during the applicable quarter but that the actual deductions of such items for such quarter may not finally be known until after Distributor makes a payment to Manufacturer under Section 3.3(b) for such quarter. Accordingly, on an ongoing
basis, Distributor shall compare actual deductions for such items against the accruals for such items used to calculate payments under Section 3.3(b) in prior quarters. Within ******(***) days after the end of each calendar quarter, Distributor
shall provide to Manufacturer (in accordance with the Accrual Rollforward Report included in Exhibit 3.2(b)) a

8

CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION,
WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH AN ASTERISK ***, HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION

rollforward of accrual activity during the previous quarter. Such rollforward shall show accruals at the beginning of the period, additions to accruals, actual charges against such accruals, any
adjustments to accruals deemed necessary by Distributor, and ending accruals held by Distributor at the end of the calendar quarter. Any adjustments to existing accruals shall be included in the computation of Net Sales in the month following the
distribution of the accrual analysis.

(c) Upon the expiration or termination of this Agreement,
Distributor shall continue to provide Manufacturer with an Accrual Rollforward Report as provided above until all adjustments to existing accruals are determined, and within *** (***) days after Distributor delivers each such Accrual Rollforward
Report, (i) if Distributor reports a decrease in amounts previously accrued, Distributor shall pay Manufacturer the resulting increase in Manufacturers share of Net Distributable Profits, and (ii) if Distributor reports an increase
in amounts previously accrued, Manufacturer shall pay Distributor the resulting decrease in Manufacturers share of Net Distributable Profits. Nothing contained herein shall require Manufacturer to pay any disputed amounts set forth in such
report or notice, or otherwise constitute a waiver of any right of Manufacturer to dispute the amounts set forth in such report or notice.

3.3 Quarterly Payment of Net Distributable Profits. During the period commencing after the First Commercial Sale and continuing thereafter until the end of the calendar quarter in which this
Agreement terminates or expires:

(a) Within *** (***) days after the end of each calendar ***, ending
after the Commencement Date, Distributor shall deliver to Manufacturer a written report, showing with respect to the immediately preceding *** (i) inventory of Product in Distributors distribution facilities as of the first and last days

the transaction that is the subject of this Agreement and their aspirations for success. In such conversations and writings, individuals representing the Parties may have expressed their judgments and beliefs concerning the intentions, capabilities
and practices of the Parties, and may have forecasted future events. The Parties recognize that such conversations and writings often involve an effort by both sides to be positive and optimistic about the prospects for the transaction. However, it

jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be
